This chapter summarizes the most common problems you could encounter with the
appliance. If you are unable to solve the problem with the information below, contact
the Consumer Care Center in your country.
Problem Possible solution
The air purier
does not work
even though it is
plugged into the
power socket and
switched on.
• Check if the top cover is properly installed.
• The filter replacement light has been on continuously but
you have not replaced the corresponding filter. As a result,
the appliance is now locked. In this case, replace the filter
and reset the filter lifetime counter.
The airow that
comes out of
the air outlet is
signicantly weaker
than before.
• The pre-filter is dirty. Clean the pre-filter (see chapter
"Cleaning").
The air quality
does not improve,
even though the air
purier has been
operating for a long
time.
• Check if the packing material is removed from the filters.
• One of the filters has not been placed in the air purifier
or a filter is not placed properly. Make sure that all filters
are properly installed in the following order, starting with
the innermost filter: 1) NanoProtect filter HEPA Series 3
(FY5185); 2) NanoProtect filter Active Carbon (FY5182);
3) pre-filter.
• The air quality sensor is wet. Make sure that the air quality
sensor is clean and dry (see chapter "Cleaning").
The air purier
produces a
unpleasant smell.
• The first few times you use the appliance, it may produce
a plastic smell. This is normal. However, if the appliance
produces a burnt smell, contact your Philips dealer
or an authorized Philips service center. The filter may
produce smell after being used for a while because of
the absorption of indoor air. Remove the filter and place
it where it has direct sunlight and ventilation for several
hours. Re-install and try using it again. If the odor remains,
please replace the filter.
The air purier is
loud.
• If the air purifier is too loud, change the fan speed to a
lower fan speed level. When using the air purifier in a
bedroom at night, choose the sleep mode.
